Exam preparation time

I have my final exams (that count for 100% of the course mark) coming up in 3 weeks (2nd week in October)

Its been a long time since I have taken any exams (5 and a half years since I graduated from University) and it does seem overwhelming agian. I had forgotten how much I used to panic before exams back in university.

Its also a bit scary that 100% of the mark is on the final exam as there were no intermediate graded assignments.
